FLAME DEFLECTOR FOR OIL BURNERS.

Application filed August 4, 1926. Serial 110.127,046.

This invention relates to an improved construction of flame deflectorfor furnaces; and has for its object to provide a flame deflectingmember adapted to be secured in a furnace and against which the flame isforced, the deflector being shaped and positioned to upwardly deflectthe flame directed against it, said defiector being lined with arefractory material capable of becoming 1ncandescent to act upon andbetter consume the fuel.

A further object of the invention is to form this flame delecting memberin the shape of the flame with an elongated scoop or trough shaped bodyportion positioned to have its flame engaging surface upwardly inclinedwith a more sharply upwardly inclined discharge end portion forcontrolling the distribution of the flame directed against the device. Astill further object of the invention is the placing between thedei'lector and the refractory material therein of a heat insulatingmaterial.

With these and other objects in view, the invention consists of certainnovel features of construction, as Will be more fully described, andparticularly pointed out iii the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation partly in section showing my improved flamedeflecting member as positioned inside of a furnace.

Figure 2 is a plan view of my improved deflecting member.

Figure 3 is a central sectional elevation of the deflecting member.

Figure 4 is a section on line 4 4 of Figure 2 looking in the directionof the arrows; and showing the secur'ing flange thereon which closesthis end.

Figure 5 is a section showing the securing bolts extending into thellanges and also showing a portion of the drain pipe as screwed into theend closing flange.

Tt is found in the operation of certain liquid fuel burning apparatus,or advantage to provide a spoon 'or trough-shaped deflecting membersecured to the inside of a furnace and against which the burning chargeis directed and to line this deflecting member with a refractor materialso that the flame of the burning uel which impinges against it will heatthis material to incandescence, thus serving to act upon and break upthe oil particles to Abetter consume the same, the deflector beingshaped to conform to the shape of the flame and positioned so as todirect properly the heat generated in the furnace to effect the mostadvantageous results. The following is a detailed description of thepresent embodiment of my invention and showing one construction ofdeflecting member by which these advantageous results may beaccomplished With reference to the drawings, 10 designates thedellecting member which is formed more or less in a trough or scoopshape and which is open on its upper side, one end of the member beingprovided with a transverse flange or end wall 11 which extends laterallyin both directions beyond the edges of the body portion of the memberand the extending ends of the flange are provided with holes 12 for thereception of securing bolts 13 by which the device is bolted in positionwithin the furnace.

This flange or end wall 11 also serves to close the lower end of thedellecting member and into this wall is tapped a drain pipe 14 whichconducts unconsumed oil back to a drip bucket (not shown).

The body portion 15 of the deflector member is positioned to be slightlyupwardly inclined, while the end portion of the body is curved moresharply upward to direct the flame as desired, about the inside of thefurnace. The discharge end portion of this member flares laterally .toconform to the fan-shape of the flame and is much wider than thereceiving end thereof also the side walls 17 at this extended dischargeend are much higher than at the receiving end so as to better hold theflame until. after the fuel mixture has been consumed and then controlits discharge against the walls of the furnace.

In order to protect the walls of this deflecting member against thedirect action of the llame forced against itand prevent the deflectorfrom radiating a large portion of heat, I first line the device with aheat-insulatin material as asbestos 18. then cover this lining with athick layer of fireclay 19 or other suitable refractory material whichis adapted to become luminous by action of the flame forced against it.This lining is locked in position by means of spurs or hook shapedmembers 20 against the walls of the device. y

My improved flame directing member is more or less of spoon-shape andserves as a firepot or mixing chamber for the burning fuel dischargedagainst it and is so shaped and by becoming upon the surrounding wallsof the furnace.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible. the invention being defined and limited only by theterms of the appended claims.

l claim:

1. A flame deiector for a liquid fuel burning apparatus comprising aspoonshaped body portion having a narrow inlet end and a-wide dischargeend, said wide discharge end being sharply upwardly inclined, said bodyportion belng lined with refractory material.

2. A Hams defiector for burning a paratus comprising a spoonshaped bo yportion having a narrow inlet end and a wide discharge end,I said widedischarge end being sharply upwardly inclined, said body portion beinglined with refractory material, and side walls extending from the inletend to the discharge end, said side walls gradually increasingr inheight from the inlet end to the discharge end.

a liquid fuel In testimony whereof I affixed my signature.
